DEVICE FOR ELEVATING WATER FROM WELLS, &G.

Specification of Letters Patent No. 30,449, dated October 23, 1860.

To all whom it may concern:

Be it known that we, SAMUEL ALDRICH and ALEXANDER ALDRIcH, both of thecity of Washington, in the District of Columbia, have invented new anduseful Improvements in Metallic Well-Curbs and Machinery for Drawing andDischarging Water, and the following is a clear and exact description ofthe same, reference being had to the accompanying drawings, making apart of this specification, in which- Figure l, shows an edge view withthe lid opened revealing the windlass and guiding roller, and the bucketand discharging arrangement in dotted lines. Fig. 2 shows a sideelevation of the curb, ratchet crank handle and brake on the face; andthe internal mechanism in dotted lines.

Our invention consists in the arrangement and combination of thebrake-lever, pawl and ratchet, for the special protection of themechanism, which will hereafter be fully specified.

To enable others skilled in the art, to make and use our improvements,we will describe it in detail referring to the drawings and the lettersmarked thereon.

We make the entire curb, or guard, of plates, of metal, of suiicientheight to have the windlass (A,) and crank (B) convenient for a personto operate easily, and of width and thickness to admit of a convenientsized bucket to pass up and down, and tip up freely, to discharge thewater. The base or bottom of the curb, is made flaring outwardsufficient to cover the opening of an ordinary sized well, and servesthe purpose of bracing and keeping it firmly in its place. The plates ofwhich the entire curb is made, may be of sheet iron of suitablethickness, riveted together, or they may be cast with small ears, andput together with bolts or rods like stove plates. They may also be madeplain or ornamental, close or open work. An inclined lid is hinged tothe top, for the purpose of opening, to come at the internalarrangements, as shown in Fig. l. The sides of the curb, form thejournal boxes (a, a,) for the shaft (5,) to the windlass (A,) to whichis attached a rope of suiicient len h, on the end of which is secured apiece o india rubber band, or belting (0,)

to which the bail (0,) of the bucket (D,) is suspended. The rope andbelt passing from the windlass over a roller (E,) by which it is guidedand brought to a position to catch under the hook (F,) and by thecontinued elevation of the bucket, the water will be accuratelydischarged into the tank (Ga) and pass off at the spout or opening (g).

On the outside of the curb, is a brake lever (H,) having a hole throughthe fulcrum end, and through which the windlass shaft (b) passes to thecrank (B,) which is provided with a ratchet wheel (6,) being cast on it,into which a pawl (f,) is pivoted to the brake-lever, and is made tohold on, or let go, by the action of the sliding rod (h), which extendsalong the brake-lever (H,) by which arrangement the whole mechanism isperfectly protected from injury by the descent of the bucket into thewell.

Cast iron for well curbs, has many and great advantages over wood, andparticularly so, for the construction and arrangement of our plan, asabove specified. In

the first place, the bottom being I'iaring, to

cover` the top of the well, it forms a substantial base to keep it inits place while the upright part can be contracted not requiring moreroom than to allow the bucket free play to discharge its contents. Italso forms a substantial frame, and boxes, for the arbors of thewindlass and guide roller, as well as the brake lever. It will notbecome warped and twisted by being frequently wet and dried, nor is itexposed to rot or decay from the eiects of the vapors arising from thewell-and lastly it can be made cheaper and more ornamental and is apermanent thing.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent isw The arrangement of thebrake-lever (H,) with the sliding rod (la) and movable pawl (f,)attached in combination with the ratchet crank-handle (B) for thepurposes herein set forth.
